South Wales tour

I've been looking at doing a tour of South Wales to include the opportunity to take in such highlights as the Hay Festival,  St David (The village with city Status), The Gower, and a few other interesting bits and pieces.  I'm happier doing three weeks or so rather than the more traditional two, but I've been looking at starting off with a cheap couple of weeks at £145 and a final week costing £104 (at 2015 prices), starting in early June to take in a couple of days of the Hay Festival. That would give anyone who only wanted a couple of weeks to join in at the start or end of the tour.  Anyone interested in joining me?
